1 Claim.

This invention relates to new and useful improvements in a magazine brush.

The invention has for an object the construction of a magazine brush which is characterized by a tubular handle adapted to receive a cartridge for` dispensing material upon the bristles of the brush.

Still further the invention particularly proposes an arrangement upon the free end of said tubular handle whereby a piston is caused to travel within the cartridge so as to dispense the material as desired.

.Still further the invention proposes a novel manner for connecting the brush upon the handle.

Another one cf the objects of this invention is an arrangement whereby the end of the handle is of a bent shape for holding the brush in a desired position.

Still further the invention proposes an arrangement Whereby the discharge from the cartridge is normally held closed except during the actual discharging operation and thereafter automatically assumes the closed position.

Still further the invention proposes the construction of a device as mentioned which is simple and durable and which may be manufactured and sold at a reasonable cost.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawing, and to the appended claim in which the various novel features of the F invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosuret- Fig. 1 is an elevational View of a device constructed according to this invention.

Fig. 'l is a fragmentary side elevational view of still another type of magazine brush.

The magazine brush according tothis invention comprises a tubular handle I with a brush II on one end and a removable plug I2 on the other end. The handle I0 is shown round in cross section though other shapes may be used, preferably this handle should be ornament-ally finished upon the outer side and may be constructed of any desirable material. The brush I I comprises a plurality of bristles mounted within a base member I3 which is hollowed out at the bottom and adapted to engage over the end of the tubular handle I0. A set screw I4 engages through the base portion I3 and serves to hold 10 the brush removably upon the end of the handle. The brush II may be of any construction and may have removable bristles or fixed bristles.

As shown the base I3 is provided with openings into which the roots of the bristles extend and wires I5 serve to removably hold the bristles in position. The plug I2 is removably mounted upon the tubular handle I Il by reason of the threaded connection. A portion of the plug is arranged outside of the tubular handle and is roughened or formed with serrations I6 for the purpose of securely gripping it so that it may readily be removed when desired.

A stem I'I is rotative through the plug I2. A packing washer I8 is located upon the inner side 25 of the plug I2. A collar I9 is fixed upon the stern I'I and is in intimate contact with the washer I8 for the purpose of holding the stem II rotative upon the plug I2 in conjunction with a knob 2E) securely attached upon the outer end of the stem and engaging against the outer face of the plug I2. 'Ihis knob also has a roughened face to facilitate its turning. v

A cartridge 2I for paste or other material is disposed within the tubular inlet I0. This cartridge has a discharge end 22 engaging through an opening in the base I3 so as to extend some ldistance among the bristles I I of the brush. The lower end of the cartridge 2| is open and a discharging piston 23 is disposed therein. This dis- 40 charging piston is provided with a packing ring 24 upon its periphery acting against the inner wall of the cartridge so as to prevent the material from the cartridge passing the edges of the piston. The discharging piston 23 is threadedly 45 engaged upon the stem I'I. 'I'he stem II is formed with left handed threads so that the knob' 20 may be rotated clockwise to cause the piston 23 to advance along the stem. The dot and dash lines 23 in Fig. 2 indicate a raised position of the 50 piston.

In Fig. 3 a cartridge has been illustrated per se and is shown in its original condition before use. Particular attention is called to the provision of a cap 25 closing the open bottom end of the car- 55 tridge which must be removed. A dotted line 26 indicates the bottom edge of the material within the cartridge so that there is a space into which the discharge piston 23 may engage when the cartridge is mounted in the magazine brush.

The operation of the device consists in first rotating the knob 20 to cause the piston 23 to move downwards to a position against the washer I9. Then the plug I2 may be removed from the tubular inlet I0 and the old cartridge removed. A new cartridge containing paste material or other similar material is then inserted within the handle so that the discharge 22 is located as distinctly shown in Fig. 2. Next the stern II is pushed through the center of the material within the cartridge and theplug I2 is reengaged at the bottomv of the handle I0. The piston 23 will assume a position within the space below the bottom edge 2B of the material in the cartridge. After the plug I2 has been reengaged upon the bottom of the handle the knob 20 may be turned to cause the piston 23 to move and force some of the material from the cartridge through the discharge neck 22 upon the bristles of the brush.

In Figs. 4 and 5 a modified arrangement of the device has been disclosed in which the invention is applied to a brush of a different design. The particular design shown may be that of a tooth brush. The tubular handle I0 is provided with a goose neck extension I0 which has its end bent at right angles. The discharge 22 from the cartridge engages partially in the goose neck I8'. The end of the goose neck is provided' with a pin 2'I adapted to engage a bayonet slot 28 upon a tubular member 29 attached at the base portion 38 of a brush having bristles 3|. These bristles are shown mounted upon a block engaged within a recess 32 formed in the base 30. Screws 33 serve to detachably secure the bristles and the block upon the base 30. The tubular member 29 is shown provided with a tubular reduced portion 34 extending through the base 30 and terminating among the bristles 3I. f

The operation of the device illustrated in Figs. 4 and 5 is substantially identical to the arrangement previously illustrated in that when the knob 20 is turned the material from within the cartridge is forced through the discharge 22 and then through the passage of the neck I0', and nally through the passage of the tubular portion 34 on to the bristles 3l. A feature of this arrangement lies in the fact that the brush may be detached from the goose neck by reason of the pin 2l and the bayonet slot 28.

In Fig. 6 another type of brush has been illustrated provided with the same invention. The casing I0 is shown provided with a goose neck I0' which is connected with the rear of a brush 35. The brush 35 is arranged transversely relative to the handle I0 and the goose neck I0 is connected to the center of the brush. In Fig. 7 the goose neck I0' of the handle I0 is shown arranged in the same plane as the brush 35. In other respects this form is similar to the form illustrated and described in Fig. 6. Attention is called to the provision of a movable hook 36 upon the tubular member 29 which is mounted upon the rear of the brush 25. This hook engages the pin 2'I for the purpose of detachably connecting the brush upon the goose neck.

In Fig. 2 it has been disclosed that the stem I'I is rotatably and slidably mounted within certain limits upon the plug I2. More particularly the collar I8 is spaced relative to the packing washer I8 and a spring 38 is interposed between these parts upon the stem. This spring 38 normally urges the stem I 'I upwards. The upper end of the stem is of conical shape and acts as a valve against the inner end seat of the discharge 22. Several small hemi-spherical projections 39 are arranged upon the inner face of the knob 20 and engage in several corresponding openings 4D upon the adjacentface of the plug I2. Normally the spring 38 maintains the stem I'I upon the seat of the discharge 22. When the knob 20 is turned for the purposeof advancing the piston 23 the projections 39 will ride out from the openings 40 and during this period the stem Il will be moved away from its seat so that the material within the cartridge may pass through the discharge 20.

While I have shown and described the preferred embodiment of my invention, it is to be understood that vI do not limit myself to the precise construction herein disclosed and the right is reserved to all changes and modications coming within the scope of the invention as defined in the appended claim.

Having thus described my invention, what I claim as new and desire to secure by United States Letters Patent isz- In a reservoir brush, a barrel, a brush held by the barrel and having a passageway discharging from the barrel into the brush, a head on the barrel, a shaft revolubly passing through the head into the barrel, a spring normally tending to shift the shaft-axially of the head toward said passageway, a knob engaged by the shaft and compressibly drawn toward the head by means of said spring, a plurality of lugs interposed between the head and the knob, whereby rotation ci the knob over the head will alternately cause the lugs on one member to drop into and be withdrawn from notches on the other member under the influence of said spring to cause a corresponding axial movement of said shaft, a piston screw-threadedly engaging said shaft, and said shaft having an end formed to open and close said passageway upon axial movement of the shaft.
